It seems that when Document Viewer Agent crashes (which in v8 does much more
than it did in 7.0.3)
it wants to restart itself, but gies all sorts of errors:

Unload Hung Screen

Module GWDCA.NLM in Address Space GWDCAW.SPGSACPO1 did not unload yet.
Killing the address space is the only way to remove the module.
Should the address space be Killed ? n

If chose Yes to the last one it then reloads, but can not bind to all sorts
of ports & dies & restarts and addresses spaces do not get unloaded/removed
If not the server will eventually run out of memory & die

Total nightmare, only way to get server back is to restart it (which I
almost never had to do with 7.0.3)
